Cm4dx nightlies

Have people been getting better battery life with the nightlies? I'm not ttoo impressed with the battery life compared to apex....

Mine actually seems to be getting worse. I adjust the build.prop to make the wifi scan 1200 seconds (if im using wifi, I know I'm near it...don't need to search every 45 seconds for it) I also adjust the maxwindows events to 80 and my vm heap to 128, but I'm not sure if that affects battery life

From what people are saying, the battery life is improving with every nightly to the point that the battery is up to par with Stock Rom.
Of course there are others that have reported that their battery life is the same or worse.
I'm not on the latest nightly, I'm on 7, but this one offered me a significantly better battery life than without them.
Since there are users that are reporting both sides of the spectrum, the only real way your going to be able to gauge battery life is by installing them yourself.
I'm hoping that someone starts a thread soon in regards to nightly details for cmda_shadow here on XDA, but your best bet for more details is the cyanogen forums or even rootzwiki where the CM4DX community is a lot greater than what it is here.

Thanks, I installed nightly 14 yesterday and the battery life has improved compared to the first release...

i had the best battery life on build 9.
also try using jrummy's android overlclock app and try running on ULV or LV.
most users have reported better battery life.

I was upto nightly 14, but just switched to a gb rom because of battery life. On cm, I had to charge at least twice a day + overnight. It was awful.

I agree battery life isn't the greatest, hopefully when we get to RC status We'll start seeing better battery life.

I think nightly eighteen has given me the best battery life thus far. I'm at 15% with 13 and a half hours. Still not what I was getting on stock though.

My battery life has been pretty even with other ROMS.
It doesn't do as well over-night (likely due to the lack of the 'night time battery saver mode' that Moto built into their roms.
Thinking about hooking up Tasker or other such program to emulate that.

I am on the 19th nightly and have not noticed much difference in battery life from the previous ones. I am running DroidX OC at ULV and am at 19+ hours with 30% battery left. I have the brightness all the way down as far as I can take it, and have used the phone moderately heavy. I read on another forum that the Minimalistic Text widget was draining batteries so I uninstalled and can tell the difference a bit. Also, for those who are under-volting their phones google around and find the best settings. The stock ULV is much higher voltage than what I am running at the moment. Best of luck to all, but I LOVE CM7!!!

I would put my phone in airplane mode overnight and it would still drain the battery. My routine became:
Pull the phone off the charger at 6 am
Put it on the car charger around 10-11 am
Back off at 3-4 pm
Charge overnight
I'm excited for the rc, but will stay on liberty aosp until then. There are many things I miss already from cm(like the notification bar toggles and up to 16 most recent apps when long pressing the home key).

I'm currently running nightly 18, I wiped my battery stats this morning at 11AM and been listening to music on and off since then, It's 8:30 right now, and I'm at 60% right now.
I'm pretty pleased with the battery life right now. Maybe as the builds continue on the battery life will get better. Compared to some over the other ROMS I've used it's pretty much even now for me.

Yeah I'm on nightly 18 and I'm liking the battery life on this one.... I read on rootzwiki that someone is trying to port over the sense 3.0 lockscreen...if that happens I'll be content with cm4dx!

[Q] Choosing a ROM, battery life a must

Hi. I'm thinking about flashing my first ROM on the Droid X. I've been using rooted GB for awhile and I'm finally just getting bored and ready to try something different. I really am not looking for much though. My order of prefs are:
Stability > Battery Life > Performance
Mods and tweaks and things of that nature are not really a huge concern for me. I just want everything to work well, and have great battery life. I'd love to hear some suggestions.

i know this is gonna sound funny maybe.
i have a vzw droid-x that i am running the alltel rom on.
i put the phone in airplane mode and enable:
wifi off never
power savings wifi always on
i get at least 24hrs
now the equivalent rom to this would be the vzw 2.2.340
if you do not enable airplane mode and disable everything else i dont see why you would not be able to get the same results.
i get amazing battery life with the rom i said i was using above and dont forget this is with an "always on wifi" never ever disconnects

DSX and Shuji are great candidates for you. DSX is not flashy. It is completely reliable and battery life is stellar. You will not be disappointed. Shuji has great battery life as well and is more customizable. My primary phone always stays on DSX though. Ran 5 straight hours of Netflix and still had 5% left. Not sure too many roms can do that.

I also run DarkSlideX and can verify what is said above. Battery life is excellent. I probably make 20-30 minutes of call a day along with 2-3 dozen texts and 2-4 hours of web, forums, etc. I'm usually off the charger around 6:30am and back on it around 9-10pm with 20-30% battery remaining.
Stability has been awesome as well. I have had one reboot in 2 months, it happened about an hour after flash and that was it. BBCrackman did an excellent job with this.
If you want to try a theme for it, wulf has made some equally as nice themes, too. There are also a few custom sliders and a crt mod, too.
Everything can be found at MyDroidWorld and each has a dedicated thread complete with instructions. Best part is you're already on the pre-rooted 596, so all you should have to do is flash DSX right on top.
EDIT: also, much of the VZW bloat has been removed and it still has some blur present. HDMI support is working, too.

Give apex a try. Very stable and fast. I usually got about 18+ hours on stock battery with heavy usage.
Sent from my SCH-I510 using XDA Premium App

I'm not quite sure how to respond to Apex and 18 hours of HEAVY usage. On a stock battery? Up till now I've never questioned someone's post, but this individual seems to have a serious question he'd like some input on. I don't have to be a modder, developer or themer to know no rom gives 18 hours of heavy use unless it's hooked up to a car battery. And even that may be questionable.

What about vanilla rom?

Thanks for the feedback guys. DSX and Shuji were a couple that had jumped out at me in my readings. I think I'll give them a shot!

Dsx was my first flash and haven't gone looking for another. Stable good battery, I'm a heavy user and smooth.
Across the airwaves via DarkslideX in 602 limbo.......

Wow. I went with darkslide and I'm loving it. I fully charged the night before last and I'm still at 50% today. That's with lower than usual usage, but still a huge improvement in battery life.

Glad you gave it a try. If you haven't already get battery calibration from Nema on the market and run that as well.

The latest cm has great battery life, and is buttery, smooth. As far as stability, and I have yet to have a problem, but but there is a slightly higher chance of issues compared to other roms.

Battery life tips?

My nexus 4 has dissapointing battery life, can someone please tell me any tips to increase the battery life? Obviously, lower the brightness, dont have too many apps running, try not to browse on chrome for too long, etc etc. Does anyone use any of the battery saving apps out there? Any tips would be appreciated. Thanks. Also, I dont understand why there are no mods/cases with an extended battery. Obviously the battery is not easily removed but I'd be fine with a thicker nexus4 if I could double my battery life.

root it and run custom ROMs and kernels, undervolt it and whatnot.
You can just buy a portable battery pack you know.. They aren't exactly expensive and serve the sane purpose as an extended battery case.

When people say that such device has got a disappointing battery life.. I wonder what it means. If a battery offers a sot of 8hrs..would this thing satisfy all?
I've used S3 which people say has got great battery life.. I got more or less the same battery life in s3 as i get from nexus 4...
Anyways..trying custom kernel and undervolting.it could give you better results..

Agreed. I have friends with s3s, one x and iphone5, and I honestly do not think the battery is bad at all. I'm pretty sure the battery lasts longer for me than for them. And I'm not one for "disabling features" either.
I'm running wifi/data both on and I never manually disable anything. My GPS is on 24/7, and I have all tracking options enabled (for google now). Using auto-brightness though. Still get 4h SOT and I stay 30+h normally without a charge. I do not game alot on my phone though!
I recently re-flashed google stock images (4.2.2) and franco's kernel. Also undervolted but if I dont get any "better" (in terms of heat) results I will definatly remove the undervolting.

This what you doing is putting up one heavy burden on the battery.Never disabling wifi/data & GPS on 24/7..Still getting 4Hrs sot out of 30hrs total battery life .If this is not great than i wonder what great would be..There is only Razor max which is gonna satisfy in terms of battery
PS->If you game a lot on Nexus 4,then the battery wont last longer

Guys u can try deep sleep battery saver app aka ds battery saver.....it puts your phone into deep sleep as soon as screen goes off.........getting 10+ hrs on single charge.......mhav a try

Have you tried Battery Guru? Developed by Qualcomm specifically for the Snapdragon S4 to improve battery life

You can try greenify, I believe the concept of this app is great and overnight on WiFi and the rest left on I loose only 2-3 percent. And wakelocks are pretty much gone.

Has CM ever had good battery life on the M?

I'm just wondering because the biggest complaint with 10, 10.1 and now 10.2 seems to have been battery life. In fact that tends to be the case for almost all of the custom ROMs with few exceptions. (uXylon has great battery life for a non-stock custom ROM, for instance).
So what likelihood is there to expect very much improved battery life on CM 10.2? Any thoughts?
BTW - this isn't a gripe on the devs' work, I really want to know what is reasonable to expect.

battery life is what you make of it - power users are going to need to a recharge during the day while casual users should be able to get through the day just fine.
in my experience, for the most part, battery life has been fairly consistent. I can go a full day (6am-11pm) on a single charge so long as I keep my on-screen time under 3 hours. this is very acceptable to me. there is no need for me to go 24 hours given that I sleep for at least 7 of them (thus, I'll charge it then)

Yeah, that's how I have seen it as well. It's all relative to how you use your phone and what your expectations are. But you know we constantly see post from guys who aren't content with battery life no matter what it is. That's why I was looking for some feedback on what is usual, customary and reasonable.

I find the battery life to be quite good. Gets me through the day and then some.
That's coming from an Xperia Play, and I've never used stock for more than a few hours.

Good to see another fellow R800x user adopt an XT907 (I've counted 5 so far)
Still waiting on official ICS...

I think this is a great question to ask. While some are content with battery life, others are not. For example, there is no way I could continue to use Liquid rom and expect any sort of reasonable battery life with how I use my phone. As much as I loved the rom itself, it simply wouldn't last long enough between charges. With AOKP I normally charge my phone in the evening (then unplug it.. Never leaving it charged overnight), and once in the afternoon and I'm good. I'm on it constantly and one charge a day with my normal usage never did it for me.. Even on stock. For some reason some roms just seem to handle battery life far better than others no matter what I am doing on my end to conserve battery power (Screen brightness, Greenify, etc). Over the weekend I was able to get 19 hours out of it with far less usage than normally since we were out enjoying the day at a winery. To me, the battery life I get with AOKP seems better or equal to what it was before unlocking the bootloader.
Sent from my Droid Razr M using xda app-developers app

as a power user im on my phone CONSTANTLY playing games and tethering and whatnot. i have to say i have found CM 10.1 roms to be quite generous on battery so far. i throw my CPU up to 1500 min/max when i plan to play COD: BOZ or Dead Trigger and ill get quite a few hours out of it off the charger before i get warned about it dying.

AOKP and Slim based ROMs have had pretty good battery life for me. When I was running CM10, it was nearly identical to stock battery life, but CM10 is 4.1.2 based. If an OEM 4.2.2 based ROM is released, they'll be able to sync it against 4.2.2 AOSP and make things work well (atleast, that's how I picture it in my head). With that being said, I am running Illusion, with Arrghh's kernel and XBreeder, and I'm sitting at about 12% battery, 36 hrs of up time, and 2.5hrs of screen on time. This is about as good as what I would see when I was running tweaked stock.
Battery life is also dependent on how long you've had your current OS running (in my experience, anyway). A lot of us around here are crackflashers and we never let a ROM settle in. I was getting average battery use on Ilusion, but it's gotten better in the last few days.

I got a new battery off amazon and been getting great battery life again. I think i borked my old one.
AOKP almost always lasts me through the day unless I go over 3 hours of screen time

Massive battery gains using ART. 100% improvement!

Hey you guys, i bought my galaxy S5 SM-G900H about 2 weeks ago and loved absolutely everything from the phone except the battery life. Coming from an Htc One Max and a OnePlus One I was used to be getting 24+ hours of battery life and with the S5 I was getting 12-15 hours tops. Im kind of a heavy user, I take pictures a lot ane constantly use wifi and my 4G data connection.
Well, to make a long story short, I tried enabling ART in my phone and now im getting 26-28 hours of battery life!! Im using the stock touchwiz rom that came with the phone and im not using any battery saver app of any sort. In other words im completely stock.
I find this improvement to be a massive one and I strongly suggest you try it.
P.S. btw everythings running smoothly with ART on my phone, no crashes whatsoever.

Something i'd overlooked, i'll give it a whirl.

I have ART enabled few weeks back, definitely improvement on battery life but have minor issues with some of the apps and experiencing a little bit of lag on my phone.

I hadn't even heard of ART until today, so I went and google'd it. I'll give it a try for a while and see how it goes. Thanks for the heads up on performance!

Actually found a negative effect since enabling ART, i usually get around a day and a half up to two days and enabling ART made it go the other way, have reverted back to Dalvic. Different strokes i suppose.

Thanks for the post. Contrary to the previous poster's opinion, which is factually mistaken, ART is well known to improve battery life. There are numerous threads that concur with the OP's experience and even Google cites that as one of the reasons that they are transitioning the Android OS to use ART instead of Dalvik as the primary cache method in the future.
At this time, it's difficult to recommend ART to Qualcom device owners as there are a number of bugs and incompatibilities that make using ART an arduous experience. However ART works better for the 900H at this time and as the OP suggests it is well worth considering if you are using an Exynos (900H) device.

Using my 900f I had quite a few issues with art on neatrom. Went back to dalvik and all good. Also started to use exposed so art isn't a viable option.
Getting about 12-18 hours fairly heavy use. More would be good but I charge nightly anyhoo.
